OIL-TANK.

Specification of Letters Patent.

Patented Ju1y'24, 190e.

Application led September 22,1905. Serial No. 279.696.

.To all? whom t mwyconoern:

Be it known that I, JOHN J. TOKHEIM, a citizen of the `United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Oil- Tank, of which the following is a specification.

This invention relates generally to oiltanks, and more particularly to one adapted for storing gasolene for use in connection with automobiles.

The object of the invention is to provide means 'whereby gasolene may be safely stored and be readily dispensed to the receiver of an automobile, the ,construction'of the apparatus being such that no waste will ensue and all danger of escape of gas will be obviated and refillingwhen necessary may be quickly and easily accomplished.

With the above and other objects in view, as will appear as the nature f the invention is better understood, the same consists in the novel construction and combination of parts of a gasolene-tank and dispensing mechanism connected therewith, as will be, hereinafter `:fully described and claimed.

In the accompanyin drawin s, forming a part of this` specificatifin, and ii which like characters of reference indicate corresponding parts,fFigure 1 is a view in elevation, partly in section, exhibiting the manner in which the gasolene tank and its appurtenances are disposed in the ground. Fig. 2 is a top plan view, on an enlarged scale, showing the use to which one part of the apparatus is put when the apparatus is not in use. Fig. 3 is a sectional detail view through the piston. Fig. 4 is a similar view throu h the valve that controls the passage of gasoIene to the place of discharge. Fig.l 5 is a top plan view of the valve shown in Fig. 4.

The apparatus consists of a tank for storing gasolene, a pump connected therewith for withdrawing the gasolene and dispensing it, means for permitting supply of gasolene and air to the tank, and means for storing the pipe or"hose used in conveying the gasolene from the tank to the automobile or the ing riveted and soldered joints in order to preclude the possibility of leakage. This tank is adapted t'o be sunk any desired distance -in the ground in order to render it harmless should it spring a leak.

- Secured tothe upper lside` of the tank at any desired' point by being riveted and soldered thereto is a casting 2, to which is bolted a casting 3, and this latter casting is engaged by the'lower end of a pipe 4, the upper end of which has secured to it a casting 5, with which is combined the lower end .of the pumpcylinder 6. The pipe 4 has secured to its lower end a pipe 7, which extends down into the tank and is provided with perorations 8 to prevent passage to the pump-cylinder of any extraneous matter that would tend to interfere with the proper operation of the pump.

, will presently appear. p

The casting -5, which,inet`eot, constitutes a nipple, has exterior threads 11, that engage with interior threads in the pump-cylinder. The upper side of the nipple has an exteriorly-threaded hollow boss 12, which is engaged by the base-ring 13 of a cage consisting of a plurality of legs k14 and an open-sided ring 14a. Arranged within the cage and resting up'on the upper face of the nipple is a gravity-valve 14h, having a .centrally-arranged boss 14c and a laterally and upwardly separated portions ofthe ring, the arm 14l constituting a valve-tripping member. The object of the extension 1()a and the arm 14d is to cause tripping of the valves 10 and 14b when the piston is pushed to its lowest point, thereby to permit any gasolene contained within the cylinder to run back into the tank, and thus prevent rotting ofthe hose which is used to convey the gasolene to the tank of the automobile. This is effected by Contact between the extension 10 and the boss 14c projecting arm 14d, that extends between the ICO - threaded connection at 17.

and the iiange ofthe piston 9 and the arm 14d when the piston is moved to the position above described.

The upper end of the cylinder connects with a chamber 15, formed on the under side of' a box 16, forming the pump-head, the cylinder being combined with the chamber by a Arranged centraly of the bottom of the pump-head is a stu ing-box 18, in which the piston-rod 19 works, a gland 20, carried by the stufIing-box, operating to secure a liquid-tight juncture between the parts. Arranged at one end of the pump-head and communicating with the chamber is a threaded nipple 21, which is designed tobe engaged b a coupling 22, carried by a hose 23, this iatter being designed to convey the gasolene from the chamber to the tank of the automobile. Communicating with the bottom of the head on the side opposite the nipple 21 are two pipes 24 and 25, the pipe 24 being the filling-pipe and the pipe 25 the vent-pipe, and these two pipes are threaded into the casting 3 and communicate with the tank through openings in the casting 2, the upper end of the filling-pipe being closed by a cap 26 and the like end of the vent-pipe being closed b a cap 27.

As shown in Fig. 2, tiie pump-head 16 is elongated and has rounded ends and is designed to house the hose when the apparatus is not in use,\as shown in 'the above figure,

whereby the hose will always be convenient of access and will be shielded from liability of danger or loss. The pump-head will. normally be sunk in the ground, so as not to present an obstruction, and is closed by a lid or cover 28, which will have combined with it a suitable lock to prevent tampering with the ump and other parts of the apparatus. hen the tank is to be iilled, the two caps 26 and 27 are detached and a hose or other suit-` able filling medium is inserted in the pipe 24, and as the gasolene passes to the tank therethrough the air displaced will pass out through the ppe 25. After the filling has .been complete the caps are replaced, thereby preventing escape of fumes. When the apparatus is to be used for filling the tank of an automobile, one end of the hose is placed therein and the piston-rod reciprocated by grasping the han le 29, thereby bausing the gasolene to be drawn from the tank 1 and su plied to the automobile-tank. When the.

fil ing lis com leted, the piston-rod is pushed down until t e piston reaches the bottom of the cylinder 6, whereupon the valves 10 and 14b will be tripped andallow any gasolene remaining in the hose and also any remaining in the -cylinder above the piston to escape back to the tank, thereby not only conserving the gasolene, but preventin rapid destruction of' the hose, which woul inevitably result`were the gasolene allowed to remain therein.

The improvements herein defined,l while simple in character, will be found to coactin the production of an article that will be found of' high efficiency in use and will insure a 'safety in handling gasolene not heretofore possible with the ordinary methods in vogue. Another feature of the invention is that by making the pump-head in the shape shown no kinking of the hosehoused thereby -will ensue, so that the life of the hose will be materially extended and the-loss resulting from the frequent purchase of hose will be obviated.

Having thus described the invention,what is claimed is 1 The combination with an underground tank, of a ump-c linder connected therewith, a heari) carrie bythe cylinder and disosed substantially flush with the groundiine, a nipple carried by the bottom 'of the head and communicating with the cylinder, and a hose connected with the nipple.

2. The combination with an underground tank, of a pump including a head disposed substantially flush with the ground-line Iand rovided with means for attachment to a iiose, and a filling and vent pipe connecting the head and the tank.

3. The combination with an underground tank, of a pump embodying a head disposed substantially iiush with the ground-line and for tripping the valves on vthe downwardV movement of the piston.

In testimony that I` claim the fforegoingas my own I have hereto aiixed mysignature in the presence of two Witnesses.

JOHN J. TOKHEIM.
